G120X IP20 500..690V 355KW FSH
6SL32203YH581CF0 — SINAMICS G120X 355 kW Drive Module
The "YH58" suffix in the Siemens G120X part number designates a 355 kW inverter module rated for 500–690 V three-phase operation and 529 A output current. Chassis-mount construction targets integration into cabinet enclosures rather than standalone deployment.

Electrical and Thermal Ratings
Output Current and Power Handling
The 529 A output rating corresponds to approximately 355 kW at 690 V three-phase. This current level demands dedicated short-circuit protection, correctly sized DC-link capacitors in the enclosing cabinet, and attention to busbar thermal management within the enclosure design.
Operating Temperature Range
The 0°C to 45°C ambient range is typical for enclosed-panel installations where internal temperatures can exceed room ambient by 10–20°C. Cabinet ventilation or forced-air cooling must be specified to maintain compliance; derating may be required above 40°C ambient.

- 6SL32203YH581CB0: Same 529 A and 355 kW as seed; differs only in internal variant code (suffix CB0 vs CF0). ROHS3 compliant.
- 6SL32203YH580CF0: Same 529 A and 355 kW as seed; the 580 prefix indicates a non-ROHS3 variant—confirm regional compliance requirements before selection.
- 6SL32203YH561CF0: Lower current (487 A) and reduced power (315 kW) while maintaining the same voltage window and chassis-mount form factor.
Engineering Verification Checklist
- Confirm output current (529 A) matches motor nameplate and system coordination study.
- Verify cabinet thermal modeling keeps ambient below 45°C at full load.
- Check short-circuit protective device coordination for 529 A branch.
- Validate DC-link component sizing in the enclosing cabinet per Siemens G120X guidelines.
- Confirm ROHS3 compliance requirement for target region (seed is compliant; 6SL32203YH580CF0 is not).
- Verify chassis-mount cutout and mounting hardware compatibility with enclosure design.
- Confirm control interface compatibility with upstream PLC or DCS (G120X series standard signals).
- Review grounding and PE termination requirements for chassis-mounted assembly.
